These are professional camera power adapters used on broadcast and cinema rigs to run cameras and accessories from V-lock or Anton Bauer-mounted battery systems. Capacity figures come from the product data, not web estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDV-MC2, DV-MC4, DV-MC8, DV-C1 fit:\u003c\/strong\u003e\n    All four units share the same internal battery bay geometry, voltage rail, and BMS communication protocol — one cell fits the full range without modification or adapter plates.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell under sustained load simulating continuous camera power draw. The BMS held charge distribution steady across the full discharge curve, with no premature low-voltage cutoff at the protection threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle acceptance on Hawk-Woods units:\u003c\/strong\u003e\n    After fitting, run one complete charge cycle through the Hawk-Woods unit itself before connecting to a camera rig. Some internal BMS systems in this product line need that initial cycle to correctly map the new cell's discharge curve for accurate remaining-power display.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DV-MC2 reads low capacity immediately after a fresh cell install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DV-MC2's onboard fuel gauge calibrates against a stored discharge curve from the previous cell. A new cell with a different internal resistance profile causes the gauge to read conservatively — sometimes showing 60–70% on a fully charged replacement. This is not a fault with the cell. One full charge-discharge cycle through the unit resets the fuel gauge's reference points. After that cycle, the display tracks the actual 10400mAh capacity accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePower output dropping mid-shoot with no low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS triggers a protective cutoff due to instantaneous current spike — common when a camera body and a high-draw accessory like a monitor or wireless transmitter are powered simultaneously from the DV-MC unit. The cell's protection circuit reads the combined draw as an overcurrent event and cuts output before the fuel gauge registers low voltage. Disconnect one accessory, then reconnect the Hawk-Woods unit to reset the BMS. Confirm the cell resting voltage reads above 7.2V before resuming the full accessory load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333601001562,"sku":"BWCS-NF980MU-1","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333601034330,"sku":"BWCS-NF980MU-2","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333601067098,"sku":"BWCS-NF980MU-3","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NF980MU-1.webp?v=1778212993","url":"https:\/\/batteryweb.com\/products\/hawk-woods-dv-mc2-replacement-battery-74v-10400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
